Installing Ford 300-I6 into Unimog 404

[RoJoGro]

Bought the Unimog with lots of engine parts missing and decided to install a Ford 300 Inline 6 instead (happen to have access to one).
I have seen some posts of Unimogs with this Ford engine installed and now hope someone would know links or other helpful info.
In particular I am looking for the adapterplate to mount engine onto the Unimog Tranny.
Helpful to know, the Unimog is a '65 and the 300 is from a '86 F150.
One person who has done it got the place from Pete's Place in 2000, but cannot remember where this fabricator (CNC shop perhaps) is located and if its still open.

Well, that should be interesting! Please share your progress with us.

I am using the two plates (from Ford engine and from M180 engine) to get the hole pattern into the drawing tool.

I did find the Ford 300 holepattern online, seems to match.

The 300 is a good engine.

am back on the project. Had to get the F300 rebuild and it's almost done. Good for a try-fit of the adapter plate to check on the hole pattern and the cutout location for the starter.
And found out that the hole pattern of the flywheel is not quite matching. holes are off by about 1/64". A small job for a milling machine.
The 'outer' holes are the Unimog and the inner from the F300. the center's offset is only ~0.8mm.
here the offset enlarged:


To help aligning the two flywheel I used my 3D-printer to print this:

It fits into the lager Unimog flywheel and smaller Ford flywheel center holes.

Have you considered road speed? With no overdrive transmission and axle ratios around 7.5, engine rpm needs to be high. The M180 engines are happy at 5000-6000 rpm all day, with peak hp even higher.

But you will have a great trail machine!

Not sure where you are with this project. I recently purchased a 404 with the same Ford 300 in it. The original owner installed the 300 with a C6 tranny and a 205 transfer case. It all seems to work well together. I don't know a whole lot about it, but hopefully this will show you another way to install the 300 into yours.

The previous owner must have ditched the torque tubes?

Update (sorry for the delay) I ended up deciding for the original M180 and abandon the E300 conversion.
The M180 engine I got had most of the missing parts I needed and is now in place. Some of the cooling hoses I had to make.
The current state is the Unimog has a running engine - but have not driven it yet.
The cab is off and being worked on.
I am far behind schedule but its coming together....
The tranny has to be checked out and the breaks (had to get a new master cylinder).
The air-brake booster is missing and I'll use it without for now.

if someone finds those drawing helpful, here are two DXF files, one for the original adapter and the 2nd adding the 300 holes:
However I never made anything out of them, and no guaranty for accuracy.
I used Fusion360 for the drawing and am happy to share the *.f3d files too if there is interest.
